No, eSIMCard does not provide a truly unlimited data eSIM for China. All plans that carry the word “Unlimited” in their names actually contain a fixed data allowance, such as 1GB or 2GB per day, after which the speed is reduced to 512kbps or 2000kbps. This means you will experience a throttled speed once the data limit is reached.
Travelers who need more data can choose from eSIMCard’s fixed‑data plans. For example, a 100GB plan for 30 days costs $95.67 USD, and a 100GB plan for 180 days costs $132.43 USD. Another option is a 1GB/day plan valid for 7 days at $13.21 USD (or a 2GB/day plan for 5 days at $19.26 USD). These fixed‑data plans can be more cost‑effective for users who want ample, unrestricted high‑speed data in China.
